TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent No. 557,755, dated April 7, 1896.

Application filed March 27, 1894.

To all whom it may concern.:

Be it known that I, XVALTER J. BARRON, a. citizen of the United States, and a resident of Brooklyn, in the county of Kings and State of NewYorlghave invented certain new and useful Improvements in Type-XVriting Machines, of which the following is a specication.

My invention relates to the ribbon movement, and has for its object to provide simple, durable, and effective means for automatically mowing the ribbon widthwise as well as lengthwise; and to this end it consists in the various features of construction and combinations of devices hereinafter more fully described, and particularly pointed out in the appended claims.

In the accompanying drawings, Figure 1 is a top plan view of enough of a Remington No. 2 type-wri ting machine to illustrate my invention, the paper-carriage and other necessary parts being omitted to simplify the view; and Fig. 2 is an end view of the same.

ln both views the same parts will be found designa-ted by the same numerals of reference.

1 is the top plate, (shown in dotted lines at Fig. 1,) 2, the upright framework or supporting-columns; 3, the inking-ribbon; 4, the right -hand ribbon-spool, (looking from the front of the machine,) and 5 the left-hand ribbon-spool.

6 are wire guides, one for each spool and embracing the same. Each said guide is secured to a sliding bar 7, slotted at S 8 and supported and guided by screws or pins 9 9, depending from bosses on the under side of the top plate. Both said slides 7 7 are connected together by a transverse rock-shaft 10 and upright rocker-arms 11, secured to said rock-shaft at their lower ends and loosely connected at their upper ends to said slides. The spool a is mounted to slide along a shaft 2, adapted to rotate in bearings 13, and said spool is also adapted to turn with said shaft. The spool 5 is mounted upon a shaft 14 and is adapted to turn therewith and also to slide longitudinally thereof, the said shaft being mounted in bearings 15. On the rear end of the shaft 12 is a bevel-gear 1G, and on the rear end of the shaft 14 is a bevel-gear 17.

In suitable bearings 1S at the rear of the machine is arranged a long shaft 19, disposed serial No. 505,262. (No model.)

at right angles to the spool-shafts and adapted to slide longitudinally in its bearings as well as to rotate. Said shaft is turned by a bevelgear 20, connected to the shaft or arbor of the spring drum or wheel 2l, said gear 2O meshing always with a corresponding gear on the shaft 19. Connected to the gear is a ratchet-wheel 23, with which engages a driving-pawl 2l on the face of the spring-drum, the construction and arrangement being such that when the paper-carriage is moved toward the right the pawl bobs idly over the teeth of the ratchet-wheel, which, together with the gear 20, at this time remains stationary; but when the carriage moves in the opposite direction the driving-pawl operates to rotate the ratchet-wheel and gear 20, and thus turn the shaft 19 through the gear 22. The springdrum is connected by a strap or chain to the paper-carriage, a portion of which is represented at 2G. On the shaft 19 is a bevelgear 27 to turn the spool-gear 1G, and also a bevel-gear 2S to turn the spool-gear 17.

The construction and operation of the machine thus far described will be understood by those skilled in the art to be that of the well-known Remington No. 2 type-writing machine, to which I have applied my improvements.

At the left-hand end of the shaft 19 is fixed a crank-arm 20, bearing a crank-pin 30. To this crank-pin is loosely connected one end of a pitman 31, whose opposite end is loosely connected to a pin or stud 32 near the upper end of the left-hand rocker-arm 11, and by this simple construction the said Remington machine is endowed with a new capacity-to wit, that of moving the ribbon transversely or widthwise automatically during the use of the machine. the ribbon mechanism in the Remington machine was constructed to permit of the movement of the ribbon widthwise by hand, whereby the ribbon might be used in lines running longitudinally thereof, and for this purpose the slides, the transverse rock-shaft, and the vertical rockerarms were provided in the machine.

By my improvement, at a very slight expense, existing Remington machines may therefore be converted into a machine in As is well known, heretofore TOO which the ribbon is moved automatically widthwise during the time of writing and is used in parallel lines transversely, instead of longitudinally, as heretofore, thereby increasing the life of the ribbon, as well as producing better results otherwise.

In the operation of the mechanism it will be understood that when the gears 17 and 2S are in mesh the ribbon-spool 5 will be positively driven and wind upon itself the ribbon, and that when the shaft 19 is slid endwise to disengage these gears and engage the gears 1G and 27 the spool #i will be positively driven to wind upon itself the said ribbon, the ribbon thus moving longitudinally first in one direction and then in the opposite one. A movable hook or catch 33 may be pivoted to the framework to engage grooves 34 in the shaft 19 to hold it in its adjusted positions.

The shaft 19 and the crank-arm 29 thereof always revolve in the same direction (indicated by the arrow at Fig. 2) and turn only when the carriage is traveling from right to left in the, printing of the lines. During the rotation of the crank-arm 29 the pitman is moved and the arms 11 rocked, and the slides, guides, and ribbon-spools simultaneously actuated. Since the crank-arm revolves always in one direction, it will be seen that the pitman is first pushed forwardly and then drawn rearwardly, thus operating to reciprocate the rocker-arms and the slides and causing the ribbon-spools to move back and forth on their shafts, by which of course the ribbon Vis simultaneously moved first forwardly in the direction of its width and then rearwardly. The crank moves slowly or step by step corresponding with the spacing movements of the carriage, and in practice is given about a half-revolution to one complete travel of the carriage from right to left, thus moving the ribbon substantially its whole width during this movement of the carriage. As the crank remains stationary during the return of the carriage, the ribbon of course does not move at this time; but during the next forward movement of the carriage the ribbon is moved widthwise in the opposite direction by the rotation of the crank through the pitman, rocker-arms, and ribbon-carrier, which in the particular form shown comprises the slides and the embracing-guides.

Owing to the fact that the driving-shaft 19 is in gear at all times with one or the other of the ribbon-spool shafts and operates to rotate the same and its ribbon-spool duringthe forward movement of the carriage, it will be understood that the ribbon is at this time moved lengthwise from one spool to another, and since the ribbon is simultaneously being moved crosswise it follows that the types strike the ribbon in oblique or diagonal lines instead of lines at right angles to the edges of the ribbon.

Vhat I claim as new, and desire to secure by Letters Patent, is-

1. In a type-writing machine, the combination of an inking-ribbon, independentlymounted sliding ribbon spools, elongated shafts therefor, reciprocatory ribbon-spool carriers, a pitman connected to the latter, a

driving-shaft rotating step by step during the longitudinal travel of the paper-carriage, an d a crank on said shaft connected to said pitman whereby the ribbon is moved widthwise automatically as the carriage advances.

2. In a type-writing machine, the combination of an inking-ribbon, ribbon-spool shafts, ribbon-spools adapted to turn with said shafts and to slide lengthwise of the same, a pair of slides connected to said ribbon-spools to move the same, a pair of rocker-arms attached to said slides, a pitman, a crank, and a driving-shaft.

3. In a type-writing machine, the combination of an inking-ribbon, ribbon-spool shafts provided each with a bevel-gear, ribbon-spools adapted to turn with said shafts and to slide lengthwise thereof, a pair of slides having each a depending embracing-guide, a pair of rocker-arms connected by a rock-shaft, a pitman connected at one end to one of said rocker-arms, a crank attached to a drivingshaft having a sliding movement and connected to the opposite end of said pitman, a spring-drum geared to said driving-shaft, and gears on said driving-shaft for alternately rotating the ribbon-spool shafts.
